Performance in Applications

Besides the tests estimating the integral system performance we have also carried out a few benchmarks measuring the notebooks performance in individual applications.

During video encoding with DivX 6.7 codec Santa Rosa platform appears only a little faster than Napa Refresh. The advantage only makes about 3% and is determined by higher bandwidth of the bus between the processor and the memory.

We observe almost the same situation during mp3 files encoding. Actually, processor clock frequency is very important for media content encoding tasks. You can clearly see it from the results of Lenovo Thinkpad T61 notebook that uses a 2GHz Core 2 Duo processor, while the other two notebooks have their CPUs running only at 1.8GHz or 1.83GHz.

Our Photoshop CS2 test script that processes five 5Mpixel pictures reveals minimal performance difference between Centrino Duo generations.

Faster memory subsystem helps the new Asus A8Sc notebook to outperform the older Toshiba Satellite A100-906 by only 2%.

During files archiving memory subsystem performance is of great important for higher results. Therefore, Santa Rosa is evidently ahead here. It is about 15% faster.

In this test we used a special script that prepared a video movie for posting on the popular YouTube web-site. For this movie we used four video fragments from a digital camera. A resource-hungry task like that also revealed advantages of the mobile Santa Rosa platform. Asus A8Sc outperformed its main competitor by 8%.

The final rendering tests demonstrated pretty expected results. Processor’s computational capacity is of primary importance here that is why the notebooks featuring Core 2 Duo processors with similar working frequencies showed almost identical results. And Lenovo Thinkpad T61, of course, proved faster than the others.
